HOlSTlNG-CAR.

SPECIFICATION forming part of Letters Patent -No. 290,404, datedDecember 18, 1883.

Application filed October 8, 1883. (No model.)

To all whom it may concern:

Be it known that I, LEWELLYN DANIEL DAVIS, of Salt Lake City, in thecounty of Salt Lake and Territory of Utah, have invented a new anduseful Improvement in Hoisting- Gars, of which the following is a full,clear, and exact description, reference being had to the annexeddrawings, forming part of this specification.

This invention relates to cars for hoisting ore out of an inclinedshaft; and the invention consists of the construction hereinafterdescribed and claimed.

In the drawings, Figure 1 is a side elevation of the car and part of aninclined track, and Figs. 2 and 3 are respectively front and rearelevations of the same.

A indicates an iron box, mounted in any suitable manner upon a truck, B.To opposite sides of the box are pivoted two oscillatory draw-bars, 0,having hooks D for attaching the chains E, which are connected to thecable F by a link, G.

H indicates two vertical guide-bars at the forward end of the car-box,within which the bars 0 are free to move. The truck also is providedwith a draw-bar, H, which is connected to the link G of the cable by achain,I.

The chains E and I are to be of such relative lengths that the draftwill be thrown on the draw-bar H and chain I on a horizontal track, andon the draw-bars G and chains E on an inclined track. By thisconstruction the car is adapted to be drawn either along a horizontaltrack or up an inclined track with safety, and without the need of anyspecial adjustment in passing from one such track to another.

The bars 0 are pivoted to the sides of the box at points near the rearend of the latter,

and preferably above the horizontal plane of its center, such pointsbeing beyond the center of gravity in an oblong box when the latter isinclined, as shown in the drawings.

Hoisting-cars have heretofore been provided with draw-bars pivoted tothe upper and rear part of their sides, and in other cases a chainattached to the ordinary draw-bar of the car has been connected toanother chain attached to the upper part of the car by a removable hood,the two chains being connected bars to a common cable, and adapted totake I the strain alternately 'as the track is inclined or horizontal,adapts the car for convenient use under a variety of circumstanceswithout the need of special adjustments, andthis combination is believedto be new.

The box is provided with a sliding cover,

J, which is held by cleats K, attached to the sides of the box, and issecured by a pin, L, which engages with the cover, and a keeper, M,attached to the inner surface of its rear end.

The front end of the box is made in the form of a gate, N, hinged at itsupper edge, and secured by a button, 0, which is rigidly attached to ashaft, 1?, arranged under the box, and adapted to be turned, to causethe but ton to engage the gate, by means of a hand lever, Q, which issupported outside the rear end of the box. This lever is passed througha squared hole in the rear end of shaft 1?, and has a hook, g, at itsend, which is detachably inserted into a staple, R, in the rear end ofthe truck. I

By removing the hook q from the staple R, the lever Q may be vibrated tooscillate the shaft 1? and button 0. When the hook is in the staple, theshaft 1? is thereby locked to prevent the button 0 from accidentallyturning and releasing the gate.

What I claim is 1. The'combination, with the draw-bar of a car-truck, ofa pair of draw-bars pivoted to the sides of the car-box above the truck,said draw-bars of the truck andbox being connected to a single cable,substantially as shown and described.

2. The combination, with the draw-bar of a car-truck, of a draw bar orbars pivoted to the sides of the car-box above, and to the rear of thecenter thereof, and the intermediate chains connecting said draw-barsindependently to a common cable, substantially as shown and described,and for the purpose specified.

3. The combination, with the box having a hinged gate at one end, of theshaft arranged 4. The ear-box having the hinged gate at under the box,and having a button secured one end and a sliding cover, substantiallyas thereto for holding the gate, and the lever at shown and described.

the rear end of the box, connected to said LEWELLYN DAXIEL DAVIS. 5shaft, and having a hook engaging with a Vitnesses:

staple for locking said shaft, substantially as FRED. B. CHANDLER,

specified. T1103. 0. ARMSTRONG.
